Filed: 1986-03-27
Abstract: PURPOSE:To decrease the change in the modulation sensitivity against the change in an oscillation frequency control voltage by inputting a modulation signal to a modulation variable capacitor diode and an oscillation frequency control variable capacitor diode. CONSTITUTION:Part of a modulation signal fed to the modulation variable capacitor diode 39 is attenuated by resistors 51,53 and fed to the oscillated frequency control variable capacitor diode 33 via a capacitor 55. Thus, in increasing the oscillation frequency control voltage VCON at modulation, the modulation sensitivity by the diode 39 is increased but the modulation sensitivity by the diode 33 is reduced. Thus, in selecting the attenuation by the resistors 51,53 properly, the combined modulation sensitivity is made constant and the change in the modulation sensitivity against the oscillated frequency control voltage VCON is reduced.

Filed: 1983-04-22
Abstract: PURPOSE:To improve the efficiency of a motor and to enhance the productivity of the motor by opposing two pairs of stators, disposing them at an electric angle displaced by pi/2 and exciting them at the phase different at pi/2 from both side surfaces of a rotor. CONSTITUTION:Two pairs of stator cores 1, 2 and 3, 4 disposed at both sides of a disc-shaped rotor are excited by currents having different phases of pi/2 from each other. Thus, N-poles and S-poles are alternately distributed in space at the time point on the stator teeth of the cores 1, 2 and 3, 4. Further, the position of the maximum value of the magnetic flux passed in the thicknesswise direction of the rotor is rotated upon lapse of time along the periphery by displacing the electric angle of the pairs in the circumferential direction by pi/2. In other words, a rotary magnetic field is produced. Since the torque generated at the rotor can be increased by the rotary magnetic field, it is designed that a closed magnetic path is formed through the rotor, the eddy current loss is small in the stator core, magnetic saturation is small and the leakage magnetic flux is small.
